Error Recovery Process to Re-insert an Overhung Media Cartridge

      A picker which has the "touch and feel" sensing ability to
detect any overhung cartridge sweeps across the wall of storage
receptacle columns.  After detecting a such overhung cartridge, the
said picker has the ability to correct the problem which could
otherwise lead to jamming.

      A data storage library, as illustrated in Fig. 1, has a picker
system 1 which transports cartridges 2 between storage receptacle
columns 3 and drives 4.  Sensors 5 are employed to detect any
cartridge that is not properly inserted into the storage slot.  Such
problem may occur because of the human handling of cartridges within
the library during machine service and manual importing/exporting of
cartridges directly from the storage slots.  If any of sensors 5
detects such a problem, the machine operation is halted to avoid the
damage caused by the collision between the fast moving picker and the
overhung cartridge.  The invention of this article proposes a picker
design concept that can automatically correct the above problem
without an intervention from the operator.

The picker design of this invention, as illustrated in Fig. 2,
comprises:
  o  A picker shell 6 which contains and guides the cartridge during
      operation,
  o  A gripping means 7 which is moved within the picker shell 6 in
      the X direction by the X motor 8 via the belt system 9, the
said
      gripping means 7 grabs or pushes the cartridge during picking
and
      inserting operations,
  o  A pushing means 10 which is attached to the gripping means 7 and
      is extended out of the picker shell, at either side or all
sides.
